What is Light?
... • Photoelectric Effect Explanation (A.E. – 1905) – Light is quantized… it travels in “packets” and is absorbed in this form (think of 1 cent) – Electrons in metal can only absorb light energy by absorbing one of these “quanta” (photon) – E=hf h = Planck’s Constant – If light shines on a metal, a pho ...

... b) For butadiene CH2=CH-CH=CH2, take the box length as 7.0Å and use the particle in 1-D box as model to estimate theoretically the wavelength of light absorbed when a pi electron is excited from the highest-occupied to the lowest vacant box level. If the experimental value is 2170Å, comment on your ...

HOMEWORK ASSIGNMENT 5: Solutions
... (c) Give ten distinct quantum numbers that can be assigned to an eigenstates of this H. Note that this includes sp and sn , even though they can never change. The ten quantum numbers are the three components of the center-of-mass momentum: px , py , and pz ; the orbital quantum numbers of the relati ...
